I've lived alone for about 8 years, since my youngest daughter moved out. Both my girls live in the South.
At first I really felt the lonliness. But I have stuff I enjoy doing alone; cooking, walking, gardening, online poker, oops.
I don't mind it so much any more. A couple years after my youngest moved away, I moved from a house to a condo (for economic reasons). I didn't think I'd like it as much as living in a house but the opposite has occurred. Being outside walking or gardening here in this condo complex has exposed me to many relationships; mostly just aquaintances, but it really does take the edge off the loneliness. I've also made a couple of real friendships here.
Also, I recently pretty much closed my business which was also solitary. I now work with approx 60 co-workers most of whom I enjoy.
